4.7.25 __pli
This intrinsic inserts an instruction prefetch, for example PLI, into the instruction stream
generated by the compiler. It enables you to signal to the memory system from your C
or C++ program that an instruction load from an address is likely in the near future.
Syntax
void __pli(...)
Where:
... denotes any number of pointer or integer arguments specifying addresses
of instructions to prefetch.
Restrictions
If the target architecture does not support instruction prefetching, this intrinsic has no
effect.

4.7.26 __qadd
This intrinsic inserts a QADD instruction or an equivalent code sequence into the
instruction stream generated by the compiler. It enables you to obtain the saturating add
of two integers from within your C or C++ code.
Syntax
int __qadd(int val1, int val2)
